I am wondering how is memory consistency maintained when both the NIC and GPU can read/write data from GPU memory (without CPU involvement). Thank you!

Many of the implementation details are actually simplified from the NVSHMEM source code. We trust that NVSHMEM as an official library can ensures memory safety.
